Avoid dereferencing NULL pointer possibly returned from
png_create_write_struct() (Andrew Church).
Version 1.6.3beta04 [May 6, 2013]
Version 1.6.3beta05 [May 9, 2013]
Calculate our own zlib windowBits when decoding rather than trusting the
CMF bytes in the PNG datastream.
Version 1.6.3beta05 [May 9, 2013]
Choose to use windowBits==15 or the zlib header setting via the
benign-errors setting. If benign errors are allowed, then ignore
the windowBits setting in the zlib header.
Zlib-1.2.8 and earlier don't allow us to decrease the windowBits, so
undid the improvement in beta04.
Added an option to force maximum window size for inflating. For inflate,
reverted previous fixes.
Added fixitxt and pngdeflate to the built programs and removed warnings
from the source code and timepng that are revealed as a result. Fixed
fixitxt when the chunk length is more than 65535 (untested, no test case).
Detect wrong libpng versions linked to pngdeflate, which currently
Added an option to force maximum window size for inflating, which was
the behavior of libpng15 and earlier.
Added png-fix-itxt and png-fix-too-far-back to the built programs and
removed warnings from the source code and timepng that are revealed as
a result.
Detect wrong libpng versions linked to png-fix-too-far-back, which currently
only works with libpng versions that can be made to reliably fail when
the deflate data contains an out-of-window reference. This means only
1.6 and later.

Added a call to png_set_packing()
Initialize dimension values so if sscanf fails at least we have known
invalid values.
Attempt to detect configuration issues with png-fix-too-far-back, which
requires both the correct libpng and the correct zlib to function
correctly.
Check ZLIB_VERNUM for mismatches, enclose #error in quotes
Added information in the documentation about problems with and fixes for
the bad CRC and bad iTXt chunk situations.
